BBIECIFIOATION forming part of Letters Patent No. 668,244, datedFebruary 19, 1901. Application filed June 22, 1900. Serial No. 21,222.(No model.)

To (LZZ/ whom it may concern.-

Be it known that we, ULYSSES S. WOHLGA MUTH and GEORGE H. WILLIAMS,citizens of the United States, residing at Findlay, in the county ofHancock and State of Ohio, have in vented a new and useful Apparatus forRemoving Impurities from the Water in Steam- Boilers, of which thefollowing is a specification.

Our invention is an improved apparatus for removing impurities from thewater in a steam boiler to minimize the formation of scale therein andprevent priming; and it consists in the peculiar construction andcombination of devices hereinafter fully set forth,

and pointed out in the claims.

In the accompanying drawings, Figure l is a vertical longitudinalsectional view of a portion of a steam-boiler provided with apparatheembodying our improvements. Fig. 2 is a vertical transverse sectionalView of the same. Figs. 3 and 4 are detail views.

In the embodiment of our invention we provide a pipe 1, which leads fromthe upper side of the boiler 2 to a receiving vessel 3, which we willcall a precipitator. A return-pipe 4 leads from the precipitator to apoint near the lower side of the boiler. A coupling 5 is attached to theend of the pipe 1 within the boilerand depends therefrom. The saidconpling is provided with a quarter-circular channel 6, which extends toone side thereof. A coupling member 7,Whichis curved, as shown, has itschannel 8 communicating with the 5 channel 6 of coupling 5, aground-joint 9 being formed betweensaid coupling 5 and member 7. Thelatter has an arm 10, which extends to one side thereof, and a yoke11,which connects said arm 10 with the body of the member 7. The saidarm 10 is provided with a pair of vertical cars 12. The pin 13 operatesin openings in the said ears, and the inner end of said pin is taperedand stepped in a conical recess It in the side of the coupling 5opposite the joint 9. A spring 15 is located on the pin 13 and bearsagainst the inner side of the outer ear 12 and against the stop 16, withwhich the pin 13 is provided, the function of the said spring being tokeep the coacting 5o coupling members 5 7 in engagement with each other,the pin 13, together with the ground joint 9, adapting the couplingmember 7 to swing pivotally, as will be understood.

A tubular arm 17 is attached to the coupling member 7, dependstherefrom, and is provided at its lower end with a skimmingfunnel 18,which is widened and flattened, as shown. A float 19 is attached to thetubular arm 17 and depends therefrom at a point near the lower end ofsaid tubular arm, the said float serving to maintain the skimming-funnelslightly below the surface of the water in the boiler, with the upperportion of the skimming-funnel slightly above the surface of the water.An arm 20 depends from the yoke 11 of the coupling member 7 and isdisposed substan tially at right angles to the tubular arm 17. Ascale-plate 21 is attached to the lower end of the arm 20, and thesuperficial area of said scale-plate which is submerged in the water inthe boiler is equal to the combined superficial areas of those portionsof the skimming-funnel and the float 19 which are submerged. The arm 20and scale-plate 21 counterhalance the tubular arm 17, skimming-funnel18, and float 19, and the superficial area of said scale-plate being, ashereinbefore stated, equal to the superficial areas of the submergedportions of the skimming-funnel and float the equilibrium is preservedunder all conditions, and hence the skimming-funnel is at all timesmaintained in its operative position slightly submerged in the Water inthe boiler and in position to receive the impurities which rise to thesurface of the Water.

In operation a circulation of water is maintained from the boilerthrough the tubular arm 17 and pipe 1 to the precipitator and from thelatter through the pipe 4 back to the boiler. The impurities in thewater in the boiler rise to the surface, are collected by theskimming-funnel 1S, and pass through the same into the precipitator andare there collected, as will be understood. Hence the formation of scalein the boiler is minimized by our improved apparatus and the same isalso efficient in preventing priming.

Having thus described our invention, we claim- 1. In apparatus of theclass described, a flexible tubular joint, having a tubular arm ICOprovided with a skimmingfiunnel, and a counterbalancing scale-plate,substantially as described.

2. In apparatus of the class described, a tube having a quarter-circularchannel extending to one side thereof and a seat on the side oppositethe open end of said channel, a coupling member adapted to turn on saidtube, having a channel communicating with that of the tube, and providedfurther with an extended arm and yoke, a spring-pressed pin carried bysaid arm and engaging the seat of said tube, a tubular arm leading fromsaid coupling member and carrying a skimmingfunnel, and acounterbalancing-arm attached to said yoke, substantially as described.

3. In apparatus of the class'described, a tube having a channel openingon one side, and a seat opposite the center of the open end of saidchannel, in combination with a coupling member having a channelcommunicatirig with that of the tube and jointed to and adapted to turnon said tube, and a springpressed centering-pin carried by supports withwhich said coupling memberis provided, said centering-pin engaging thesaid seat of said tube, substantially as described.

4. In apparatus for removing the impurities from water in asteam-boiler, a flexible tubular joint having a tubular arm providedwith a skimming-funnel and a float to buoy the said tubular arm andskimming-funnel, an arm and scale-plate to counterbalance the tubulararm, skimming-funnel and buoy or float, the superficial area of thescale-plate being equal to the combined superficial areas of thesubmerged portions of the skimmingfunnel and float, for the purpose setforth, substantially as described.

In testimony that We claim the foregoing as our own We have heretoaiiixed our signatures in the presence of two Witnesses.
